Streets to avoid during the Dallas Marathon this weekend

UPDATE: The Dallas Marathon has been canceled due to dangerous conditions created by Winter Storm Cleon.

--

By all accounts, the Metro PCS Dallas Marathon couldn't have picked a worse winter weekend for its 2013 edition. But the race must go on, even with a predicted 27-degree start-time temperature with a chance of freezing ran.

Should race organizers deem conditions unsafe for running, they will email participants and update the Dallas Marathon website. Barring that possibility, take note of the following road closures:

Main Street will be closed from Ervay to Houston beginning at 5 pmSaturday. Portions of Main will reopen at 10 am Sunday, with full function returning by 3 pm.
